Xylographa parallela Xylographa parallela (Ach.: Fr.) Fr.

The most common Xylographa species usually recognized by groups of oblong apothecia arranged parallel to wood fibers. It occurs mainly on hard, slowly decomposing wood of conifers in mountain areas. In relic forest stands the species descends to middle altitudes. Above the upper treeline it appears on worked wood of roofs or fences. Exceptionally also bark-dwelling on coniferous tree bases. This ecomorph, previously referred to as X. minutula, is conspecific with wood-dwelling specimens based on molecular data (Spribille et al. 2014). This boreal-montane species is quite common in mountain areas of both central Europe and the Czech Republic. A part of the historical material from the Czech Republic may belong to previously usually undistinguished species X. pallens, which is characterized by star-like groups of apothecia.
